Answer:
25x^4 + 35x^2 - 35x^2 - 49
25x^4 - 49
Answer:
(x,y)→(x,−y)
Step-by-step explanation:
I did it before
So they can sell 500 footballs or less, but not more. I'll use (x) for how many can be sold. x <span>≤ 500</span>
This is for rounding up:
So in this number, 7 is the digit in the ten thousands place. Round 7 up and you get 680000
- Product Rule of Radicals: √ab = √a × √b
So firstly, factor out i (i = √-1):
10i√80
Next, apply the product rule of radicals and simplify the radical as such:
√80 = √10 × √8 = √5 × √2 × √4 × √2 = 2 × 2 × √5 = 4√5
10i × 4√5 = 40i√5
<u>Your final answer is 40i√5.</u>
